Method for determining endotoxins in a liquid, wherein said liquid is contacted, at 20`C - 40`C, with a lysate of limule amebocytes and an aqueous solution of a peptide having the following formula (FORMULA) wherein [Pept] is a peptidic hydrophobic chain, n is 1, 2, 3, 4 or 5, B is (FORMULA) R<u1>u, R<u2>u and R<u3>u being H or CH<u3>u, [NH-Ar] is the residue of a fluorescent heteroaromatic amine and X<s0>s is an anion, the pH of the thus obtained medium is adjusted at 5 to 10 and the heteroaromatic amine thus formed is determined; and new peptides according to formula (I) usable in said method. |
